APPARATUS FOR PITCHlNG BARRELS.

SPECIFICATION forming part of Letters Patent No. 385,178, dated June 26,1888.

(No model.)

To aZZ whom it may concern:

Be it known that we, LOUIS HAGGENMILLER and OTTO HAGGENB'IILLER,citizens of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulImprovement in Apparatus for Pitching Barrels, which im provement isfully set forth in the following specification and accompanyingdrawings.

Our invention relates to improvements for pitching barrels and similararticles.

It consists in a novel form of apparatus for injecting dry orsuperheated steam and air into a barrel, and is so arranged that thesteam is carried from an adjacent boiler to a superheating steam-jacket,and afterward mingled with inflowing air, the same being then injectedthrough the body of a furnace into the barrel or article to be pitched.

Prior to our invention it was old in the art of pitching barrels toinject mingled superheated steam and air into and through a furnace, andultimately to the inner surface of the barrel or article to be pitched,through the agency of separate steam and air pipes, the furnaceconnected to a boiler, and the latter to a fan or blower.

It is the especial. object of our invention to simplify this apparatusby utilizing the injecting force of the steam from the boiler, andcausing it to draw the air after or with it through the furnace.

The invention will be better understood by reference to the accompanyingdrawings, in which Figure 1 represents a side elevation of our improvedapparatus, showing parts thereof in section. Fig. 2 represents ahorizontal crosssection thereof, taken on line mm, Fig. 1. Fig. 8represents a similar section taken on line y 3 Fig. 1. Fig. 4trepresents a vertical section on line z 2, Figs. 2 and 3.

Similar letters of reference indicate 'corre sponding parts in theseveral figures.

Referring to the drawings, A represents the body of the furnace,havingthe usual grate, and P is an air or draft pipe extending from theside of the superheating-chamber E, as shown in Figs. land 3, to thebase of the furnace beneath the grate.

T represents a steam-pipe, connected at one end to an adjacent boiler,(not shown) and at the other to a steam jacket, G, encompassing thefurnace-chamber A. This steamjacket is divided by a solid wall, \V, andhas an outletpipe, T, extending downward into the air-pipe P, andprovided with injectonnozzles I. The air-chamber E has inlets oropenings F F, to admit air into it, as shown in Fig. 3.

P represents the exit-nozzle for the super heating steam and air afterit has passed through the furnace, and B the barrel to be pitched.

The operation is as follows: A tire is started in the furnace and steamadmitted into pipe T in the directionof the arrows. As the steam passesthrough the jacket or superheatingchamber 0 in the direction of thearrows, it is heated, and emergesultimately through the injector-nozzlesI into the air-pipe P, where it draws with it, after the manner of aninjector, the superheated air from chamber or jacket E, as shown by thearrows atF F. In this manner dry or superheated air and steam are forcedthrough the furnace, giving increased combustion, and thereforeadvantageous heat, at the nozzle or pipe P, where'the heat is utilized.

The hood D, to which the exit'noz'zle is attached, has an inlet forsupplying fuel to the furnace, said inlet being closed by a cap or plug,D.

Having thus described our invention, what we claim as new,and desire tosecure by Letters Patent, is-

1. In a device for pitching barrels, a fur nace having a steam-injectionpipe connected to a superheating-jaeket, in combination with an air-pipeconnected to a second superheating-jacket, the air-pipe surrounding theinjection-pipe and connected to the base of the furnace at a point beiowthe bed of the fire, substantially as described.

2. In a device for pitching barrels, two superheating-jackets arrangedin close proximity to a furnace, in combination with a steam-injectionpipe and an air-pipe, each connected to one of saidsuperheatirig-jackets, and so arranged that the admission of steamthrough the injector forces intermingled superheated steam ICC a furnacewith hcod having a nozzle, an airjector being connected, respectively,to superto heating chamber with ainpipe leading thereheating chambersand jackets, substantially as from into the base of the furnace, andasteamdescribed.
